[Hallicrafters] On Off switch fun

[Ka9p at aol.com]

Hi.  Does anyone know of a source for the on/off switch that resides  on 
the end of the function switch in many of the Hallicrafters receivers like  
the SX series, or sell a junker switch to sell? 
 
I have one that took a whack on the function knob in shipping, smashing the 
 switch up against the hardware behind it, happily everything else on the 
switch  shaft is ok, but the on/off function is permanently, off :(
 
Thanks, Scott
